The sample size calculation can be performed when the plan is to use a non-parametric test for testing a one-sided (superiority, non-inferiority), two-sided (difference), or two one-sided (quivalence) hypothesis. For most of the tests, a power comparison can be made assuming different underlying parametric distributions in Monte Carlo simulations.
